I can recommend the
501 LED Super Bright White for the front position lights (£15.99 pair from
www.autobulbsdirect.co.uk ).
These give a brilliant bright white light as opposed to the dull yellowy look to the standard or the 'blue' 5w bulbs. Click on this link to see the difference:

Ps: I've fitted these in the front map lights as well. They go better with the rear centre light I've replaced with the LED festoon.
